Splinting, Thumb Spica
Updated: May 5, 2009
Introduction
In general, splints are applied to decrease movement and provide support and comfort through stabilization of an injury.1 Splints are primarily used to secure nonemergent injuries to bones until they can be evaluated by a consultant such as an orthopedic surgeon. Splints are also used to temporarily immobilize an extremity prior to surgery (eg, open fracture) or to assist in primary healing. Unlike casts, splints are noncircumferential and often preferred in the emergency department setting, since injuries are often acute and continued swelling can occur. All patients with injuries that are splinted should be referred for evaluation by a consultant in a timely fashion (usually within 2-7 days, depending on the reason for the splint).
Indications
A thumb spica splint can be used for various injuries that include the following:
- Scaphoid injuries
- Lunate injuries
- First metacarpal fractures
- Injury to the ulnar collateral ligament
- Positioning for de Quervain tenosynovitis
Contraindications
- Absolute contraindications – None
- Relative contraindications in injuries that require immediate evaluation or intervention by a consultant (eg, orthopedic surgeon, hand surgeon, plastic surgeon)
- Complicated fractures
- Open fractures
- Injuries with associated neurovascular compromise
